| 摘 要： | ICP发射光谱法测定矿样中痕量稀土分量本文讨论了以ICP-AES法测定矿样中痕量稀土元素分量方法.实验曾借鉴岩矿测试所的方法.此方法是将试样经阳离子交换富集,浓缩至小体积,加入内标后,通过气动雾化器将溶液输送到ICP激发,摄取光谱.不同稀土元素的检出限分别为0.00X～0.Xμg/g各被测元素光谱测定相对标准偏差为1.8～4.1%.经GSD-1～GSD-8标样三次分析,以及经半年多来五批样品的生产实践证明,本方法流程简单,分析速度快,易于推广,检出限和精确度基本上能满足需要.

| Abstract: | The determinatioon of trace REE by ICP-AES method is discussed in this paper. The REE in samples were preconcentrated through ion-exchange process, and introduced to the ICP using a pneumatic nebulizer. An axially-viewed (end-on) plasmatorch was also selected. The detection limit and analytical accuracy can meet the demands of trace REE analysis. |
